Description

本発明は、調湿システムに関し、特に、除湿装置から室内へ供給される空気の温度制御に係るものである。     The present invention relates to a humidity control system, and particularly relates to temperature control of air supplied from a dehumidifier to a room.

従来より、室内等を除湿する除湿装置が広く知られている。除湿装置として、2つの吸着素子を備え、各吸着素子で交互に空気を除湿するものがある。     Conventionally, a dehumidifying apparatus for dehumidifying a room or the like is widely known. Some dehumidifying devices include two adsorbing elements, and each adsorbing element alternately dehumidifies air.

特許文献1には、この種の除湿装置が開示されている。この除湿装置は、ケーシング内の空気通路に第1吸着素子と、第2吸着素子とが区画されて配置されている。吸着素子は、空気が流通可能な基材に水分を吸脱着する吸着剤が担持されている。また、ケーシング内には、各吸着素子の空気の上流側に空気を加熱するための凝縮器(加熱手段)が設けられている。     Patent Document 1 discloses this type of dehumidifying device. In this dehumidifier, a first adsorbing element and a second adsorbing element are partitioned in an air passage in the casing. In the adsorption element, an adsorbent that adsorbs and desorbs moisture is supported on a base material through which air can flow. Further, a condenser (heating means) for heating the air is provided in the casing on the upstream side of the air of each adsorption element.

特許文献1に開示される除湿装置では、以下のような2つの動作が交互に行われる。まず第1動作では、第1吸着素子で空気中の水分が吸着され、空気が除湿される。除湿された空気は室内へ供給される。また、第1動作では、凝縮器で加熱された空気が第2吸着素子へ供給され、第2吸着素子が加熱される。その結果、第2吸着素子から空気中へ水分が放出され第2吸着素子の再生が行われる。第2吸着素子の再生に利用された空気は、室外へ排出される。一方、第2動作では、第2吸着素子で空気中の水分が吸着され、同時に第1吸着素子の再生が行われる。以上のように、この除湿装置では、第1動作と第2動作とを所定時間置きに切り換える、いわゆるバッチ運転を行うことで、各吸着素子の吸着性能(即ち、除湿性能)を低下させることなく、室内の空気を連続的に除湿できるようにしている。
特開2004−60954号公報
In the dehumidifying device disclosed in Patent Document 1, the following two operations are alternately performed. First, in the first operation, moisture in the air is adsorbed by the first adsorption element, and the air is dehumidified. The dehumidified air is supplied into the room. In the first operation, air heated by the condenser is supplied to the second adsorption element, and the second adsorption element is heated. As a result, moisture is released from the second adsorption element into the air, and the second adsorption element is regenerated. The air used for the regeneration of the second adsorption element is discharged outside the room. On the other hand, in the second operation, moisture in the air is adsorbed by the second adsorption element, and at the same time, the first adsorption element is regenerated. As described above, in this dehumidifier, by performing so-called batch operation that switches between the first operation and the second operation every predetermined time, the adsorption performance (that is, dehumidification performance) of each adsorption element is not lowered. The indoor air can be dehumidified continuously.
JP 2004-60954 A

上述したように、2つの動作を交互に行う除湿装置では、再生側の吸着素子から水分を放出させるために、加熱手段で加熱された空気を供給して吸着素子を昇温させている。このため、上記2つの動作(バッチ動作)の切り換え直後には、再生側から吸着側へ遷移した吸着素子が未だ比較的高温になっていることがある。その結果、バッチ動作の切り換え直後には、比較的高温の空気が室内へ供給されてしまうという問題が生じる。     As described above, in a dehumidifying apparatus that performs two operations alternately, in order to release moisture from the adsorption element on the regeneration side, air heated by the heating means is supplied to raise the temperature of the adsorption element. For this reason, immediately after switching between the two operations (batch operation), the adsorption element that has transitioned from the regeneration side to the adsorption side may still be at a relatively high temperature. As a result, there is a problem that air of relatively high temperature is supplied into the room immediately after the batch operation is switched.

この点について、図7を参照しながら詳細に説明する。同図において、Taは、加熱手段で加熱された後の空気の温度(即ち、吸着素子の再生温度)の経時変化を示し、Tbは、室内へ供給される空気(供給空気)の温度の経時変化を示し、各破線はバッチ動作の切り換え時点を示している。同図から明らかなように、吸着素子は60℃前後まで加熱される。このため、再生側の吸着素子が次の動作で吸着側の吸着素子へ遷移すると、その切り換え直後には、吸着側の吸着素子が未だ約60℃に近い温度となっている。従って、バッチ動作の切り換え直後には、供給空気の温度が最高温度(約45℃)となり、その後、吸着側の吸着素子が徐々に冷やされて低下していく。そして、バッチ動作の終了間際には、供給空気の温度が最低温度(約35℃)となる。その後、次のバッチ動作が行われると、供給空気の温度が再び最高温度となる。     This point will be described in detail with reference to FIG. In the figure, Ta represents the change over time in the temperature of the air after being heated by the heating means (that is, the regeneration temperature of the adsorption element), and Tb is the change over time in the temperature of the air supplied to the room (supply air). A change is shown and each broken line has shown the switching time of batch operation. As is apparent from the figure, the adsorption element is heated to around 60 ° C. For this reason, when the regeneration-side adsorption element transitions to the adsorption-side adsorption element in the next operation, immediately after the switching, the adsorption-side adsorption element is still at a temperature close to about 60 ° C. Therefore, immediately after the switching of the batch operation, the temperature of the supply air reaches the maximum temperature (about 45 ° C.), and thereafter, the adsorption element on the adsorption side is gradually cooled and lowered. And just before the end of the batch operation, the temperature of the supply air becomes the lowest temperature (about 35 ° C.). Thereafter, when the next batch operation is performed, the temperature of the supply air becomes the maximum temperature again.

以上のように、従来の除湿装置の各バッチ動作では、再生側の吸着素子に残存する熱の影響により室内へ供給される空気の温度が大きく変動してしまう。その結果、室内温度を一定に保つことができず、温度環境が損なわれてしまう。また、半導体工場のクリーンルームや食品工場等、比較的高い精度での温度制御(例えば±2℃)の要求が課せられる空間の除湿に、上記の除湿装置を適用することが考えられる。このような場合に供給空気の温度が大きく変動すると、所望とする温度制御を行うことができず、品質管理に多大な支障をもたらしてしまうという問題があった。     As described above, in each batch operation of the conventional dehumidifier, the temperature of the air supplied to the room greatly fluctuates due to the influence of the heat remaining in the regeneration side adsorption element. As a result, the room temperature cannot be kept constant, and the temperature environment is impaired. In addition, it is conceivable to apply the above dehumidifying device to dehumidifying a space where a requirement for temperature control (for example, ± 2 ° C.) with relatively high accuracy is imposed, such as a clean room or a food factory in a semiconductor factory. In such a case, if the temperature of the supply air largely fluctuates, the desired temperature control cannot be performed, and there is a problem that the quality control is greatly hindered.

本発明は、斯かる点に鑑みてなされたものであり、除湿装置から室内へ供給される空気の温度変動を抑制することを目的とする。     This invention is made | formed in view of such a point, and it aims at suppressing the temperature fluctuation of the air supplied indoors from a dehumidifier.

内部を空気が流れるケーシング(11)と、該ケーシング(11)の内部に設けられ、空気中の水分を吸着する2つの吸着素子(61,62)と、上記ケーシング(11)に設けられ、上記吸着素子(61,62)に供給される空気を加熱する加熱手段(45)とを備え、上記第1吸着素子(61)で水分を吸着した空気を室内へ供給すると共に、上記加熱手段(45)で加熱した空気を第2吸着素子(62)に通過させて室外へ排出する第1動作と、上記第2吸着素子(62)で水分を吸着した空気を室内へ供給すると共に、上記加熱手段(45)で加熱した空気を第1吸着素子(61)に通過させて室外へ排出する第2動作とを交互に切り換えて実行する除湿装置(10a)を複数台有する調湿システムであって、上記複数台の除湿装置(10a,10b,10c)のそれぞれの第1動作および第2動作を切り換える切換動作をそれぞれ異なった時間で実行するように制御する制御手段(80)と、該各除湿装置(10a,10b,10c)から室内へ供給する空気を集合する空気集合手段(90)とを備えている。     A casing (11) through which air flows, two adsorbing elements (61, 62) that are provided inside the casing (11) and adsorb moisture in the air, and provided in the casing (11), Heating means (45) for heating the air supplied to the adsorption elements (61, 62), and supplying the air adsorbed with the first adsorption element (61) into the room, and the heating means (45 ), The first operation of passing the air heated by the second adsorbing element (62) and discharging it to the outside, and supplying the air adsorbed moisture by the second adsorbing element (62) into the room, and the heating means A humidity control system having a plurality of dehumidifiers (10a) for alternately switching and executing the second operation of passing the air heated in (45) through the first adsorption element (61) and discharging it to the outside, First operation and second operation of each of the plurality of dehumidifiers (10a, 10b, 10c) Control means (80) for controlling the switching operation for switching between different times, and air collecting means (90) for collecting the air supplied from the dehumidifiers (10a, 10b, 10c) to the room, It has.

上記第1の発明では、各除湿装置(10a,10b,10c)のそれぞれの第1動作を第2動作に切り換える切換動作、またはそれぞれの第2動作を第1動作へ切り換える切換動作を、各除湿装置(10a,10b,10c)が、それぞれ異なった時間で実行する。このため、各除湿装置(10a,10b,10c)から供給される空気の温度は、それぞれ異なった空気温度となる。次に、空気集合手段(90)は、上記各除湿装置(10a,10b,10c)から供給される空気を集めて混ぜ合わせる。これにより、空気集合手段(90)において空気温度は各除湿装置(10a,10b,10c)から供給される空気の平均温度になる。その後、空気集合手段(90)から、混ぜ合わせた空気を室内に供給する。     In the first aspect, each dehumidifying device (10a, 10b, 10c) is switched to the second operation or the switching operation to switch the second operation to the first operation. The devices (10a, 10b, 10c) execute at different times. For this reason, the temperature of the air supplied from each dehumidifier (10a, 10b, 10c) becomes a different air temperature. Next, the air collecting means (90) collects and mixes the air supplied from the dehumidifying devices (10a, 10b, 10c). Thereby, in the air collecting means (90), the air temperature becomes the average temperature of the air supplied from each dehumidifier (10a, 10b, 10c). Thereafter, the mixed air is supplied into the room from the air collecting means (90).

第2の発明は、上記第1の発明において、上記制御手段(80)は、各除湿装置(10a,10b,10c)の上記切換動作を、複数台の除湿装置(10a,10b,10c)が所定時間間隔を置いて順に実行するよう制御する。     In a second aspect based on the first aspect, the control means (80) is configured so that the dehumidifying devices (10a, 10b, 10c) perform the switching operation of the dehumidifying devices (10a, 10b, 10c). It controls to execute in order at predetermined time intervals.

上記第2の発明では、第1動作から第2動作、または第2動作から第1動作へ切り換える切換動作を、複数台の除湿装置(10a,10b,10c)が、所定時間間隔を置いて順に実行する。次に、空気集合手段(90)は、各除湿装置(10a,10b,10c)から供給される空気を集めて混ぜ合わせる。これにより、空気集合手段(90)において空気温度は各除湿装置(10a,10b,10c)から供給される空気の平均温度になる。その後、空気集合手段(90)から、混ぜ合わせた空気を室内に供給する。     In the second invention, the switching operation for switching from the first operation to the second operation or from the second operation to the first operation is performed in order by the plurality of dehumidifiers (10a, 10b, 10c) at predetermined time intervals. Execute. Next, the air collecting means (90) collects and mixes the air supplied from the dehumidifying devices (10a, 10b, 10c). Thereby, in the air collecting means (90), the air temperature becomes the average temperature of the air supplied from each dehumidifier (10a, 10b, 10c). Thereafter, the mixed air is supplied into the room from the air collecting means (90).

上記第1の発明は、各除湿装置(10a,10b,10c)における切換動作(第1動作から第2動作、または第2動作から第1動作)を、それぞれ異なった時間で実行するようにした。このため、各除湿装置(10a,10b,10c)から供給される空気の温度は、それぞれに異なった空気温度となる。また、空気集合手段(90)を設けたため、各除湿装置(10a,10b,10c)から供給される空気を集めることができる。このため、各除湿装置(10a,10b,10c)から供給される、異なった温度の空気を空気集合手段(90)において混ぜ合わせることができる。つまり、空気集合手段(90)では、常に異なる温度の空気を混ぜ合わせることになるため、空気集合手段(90)における平均空気温度の変動は抑制される。これにより、混ぜ合わされて温度が平均化した空気を室内へ供給することができる。この結果、除湿装置(10a,10b,10c)から室内へ供給される空気の温度変動を抑制することができる。     In the first invention, the switching operation (first operation to second operation, or second operation to first operation) in each dehumidifier (10a, 10b, 10c) is performed at different times. . For this reason, the temperature of the air supplied from each dehumidifier (10a, 10b, 10c) becomes a different air temperature. Moreover, since the air collecting means (90) is provided, the air supplied from each dehumidifier (10a, 10b, 10c) can be collected. For this reason, the air of different temperature supplied from each dehumidifier (10a, 10b, 10c) can be mixed in the air collecting means (90). In other words, since the air collecting means (90) always mixes air having different temperatures, fluctuations in the average air temperature in the air collecting means (90) are suppressed. Thereby, the air which was mixed and the temperature was averaged can be supplied indoors. As a result, temperature fluctuations of the air supplied from the dehumidifiers (10a, 10b, 10c) to the room can be suppressed.

上記第2の発明は、各除湿装置(10a,10b,10c)のそれぞれの切換動作を、複数台の除湿装置(10a,10b,10c)が、所定の時間の間隔を置いて順に実行するようにした。このため、各除湿装置(10a,10b,10c)から供給される空気は、時間間隔によって、それぞれが所定の温度差を持つことになる。つまり、空気集合手段(90)で混ぜ合わされる空気は、それぞれの温度関係が一定になるため、混ぜ合わされた空気の平均温度も一定になる。これにより、混ぜ合わされて温度が平均化した空気を室内へ供給することができる。この結果、除湿装置(10a,10b,10c)から室内へ供給される空気の温度変動を抑制することができる。     In the second aspect of the invention, the switching operation of each dehumidifying device (10a, 10b, 10c) is sequentially performed by a plurality of dehumidifying devices (10a, 10b, 10c) at predetermined time intervals. I made it. For this reason, the air supplied from each dehumidifier (10a, 10b, 10c) has a predetermined temperature difference according to the time interval. That is, since the air mixed by the air collecting means (90) has a constant temperature relationship, the average temperature of the mixed air is also constant. Thereby, the air which was mixed and the temperature was averaged can be supplied indoors. As a result, temperature fluctuations of the air supplied from the dehumidifiers (10a, 10b, 10c) to the room can be suppressed.

The air flowing into the second adsorption chamber (52) passes through the second adsorption element (62). In the second adsorption element (62), moisture (water vapor) contained in the air is adsorbed by the adsorbent. As a result, in the second adsorption element (62), air is dehumidified by such an adsorption operation. The air dehumidified by the second adsorption element (62) flows out from the fourth supply side damper (78) to the supply passage (28) and is blown into the room as supply air (SA).

第2吸込口(22)から第2吸込通路(27)へ取り込まれた第2空気は、熱交換器(45)を通過する。熱交換器(45)では、温水と空気とが熱交換し、空気が約60℃程度まで加熱される。熱交換器(45)で加熱された空気は、第1給気側ダンパ(75)より第1吸着室(51)へ流入する。第1吸着室(51)へ流入した空気は、第1吸着素子(61)を通過する。第1吸着素子(61)の吸着剤は、空気によって加熱される。その結果、第1吸着素子(61)では、このような再生動作によって接着剤に吸着された水分が空気中へ放出される。第1吸着素子(61)の水分を奪った空気は、第2排気側ダンパ(72)より排気通路(26)へ流出し、排出空気(EA)として室外へ排出される。     The second air taken into the second suction passage (27) from the second suction port (22) passes through the heat exchanger (45). In the heat exchanger (45), the hot water and air exchange heat, and the air is heated to about 60 ° C. The air heated by the heat exchanger (45) flows into the first adsorption chamber (51) from the first supply side damper (75). The air that has flowed into the first adsorption chamber (51) passes through the first adsorption element (61). The adsorbent of the first adsorbing element (61) is heated by air. As a result, in the first adsorption element (61), the moisture adsorbed on the adhesive by such a regeneration operation is released into the air. The air deprived of moisture from the first adsorption element (61) flows out from the second exhaust side damper (72) to the exhaust passage (26) and is discharged to the outside as exhaust air (EA).

本実施形態の除湿装置(10a,10b,10c)では、上記第1バッチ動作と第2バッチ動作とを交互に行うことで、各吸着素子(61,62)の吸着剤で水分が飽和する(吸着過多になる)ことなく、連続的に室内を除湿することができる。ところが、このように第1バッチ動作と第2バッチ動作を切り換えると、各バッチ動作の切り換え直後には、再生側から吸着側へ遷移した吸着素子(61,62)が未だ比較的高温となっていることがある。その結果、各バッチ動作の切り換え直後において、比較的高温の空気が供給空気(SA)として室内へ供給されてしまう。     In the dehumidifying device (10a, 10b, 10c) of the present embodiment, moisture is saturated with the adsorbent of each adsorbing element (61, 62) by alternately performing the first batch operation and the second batch operation ( The room can be dehumidified continuously without excessive adsorption). However, when the first batch operation and the second batch operation are switched in this way, immediately after the switching of each batch operation, the adsorption elements (61, 62) that have transitioned from the regeneration side to the adsorption side are still relatively hot. There may be. As a result, immediately after switching between batch operations, relatively high-temperature air is supplied into the room as supply air (SA).

具体的には、除湿運転において、例えば第1バッチ動作から第2バッチ動作へ切り換えられると、第1バッチ動作の終了直後には、第1バッチ動作で再生側となる第2吸着素子(62)が約60℃まで昇温されている。このような状態で、次の第2バッチ動作が行われると、吸着側に遷移する第2吸着素子(62)が未だ高温となっており、この高温状態の第2吸着素子(62)を通過した空気が室内へ供給されてしまう。その結果、第2バッチ動作の直後には供給空気(SA)の温度が比較的高温になり、その後に第2バッチ動作を継続するに連れて第2吸着素子(62)が冷却されて、供給空気(SA)の温度が低くなっていく。     Specifically, in the dehumidifying operation, for example, when switching from the first batch operation to the second batch operation, immediately after the end of the first batch operation, the second adsorbing element (62) that becomes the regeneration side in the first batch operation. Is raised to about 60 ° C. In this state, when the next second batch operation is performed, the second adsorption element (62) transitioning to the adsorption side is still at a high temperature, and passes through the high temperature second adsorption element (62). Air is supplied to the room. As a result, the temperature of the supply air (SA) becomes relatively high immediately after the second batch operation, and then the second adsorption element (62) is cooled and supplied as the second batch operation is continued. The temperature of air (SA) is getting lower.

以上のように、各除湿装置(10a,10b,10c)における除湿運転では、各バッチ動作の開始直後に供給空気(SA)が最高気温となり、バッチ動作を継続するに連れて供給空気(SA)が低くなっていく。このため除湿運転では、供給空気(SA)の温度変動が大きくなり、室内の温度を一定に保つことができなくなる。     As described above, in the dehumidifying operation in each dehumidifying device (10a, 10b, 10c), the supply air (SA) becomes the maximum temperature immediately after the start of each batch operation, and the supply air (SA) as the batch operation continues. Is getting lower. For this reason, in the dehumidifying operation, the temperature fluctuation of the supply air (SA) becomes large and the indoor temperature cannot be kept constant.

そこで、本実施形態の調湿システム(1)では、各除湿装置(10a,10b,10c)での第1バッチ動作と第2バッチ動作との切り換え時間を、それぞれが所定時間間隔を置いて実行すると共に、各除湿装置(10a,10b,10c)から供給される供給空気(SA)をチャンバ(90)で集めて混ぜ合わせることで、室内に供給される空気の温度変動を抑えるようにしている。     Therefore, in the humidity control system (1) of the present embodiment, the switching time between the first batch operation and the second batch operation in each dehumidifier (10a, 10b, 10c) is executed at predetermined time intervals. At the same time, the supply air (SA) supplied from each dehumidifying device (10a, 10b, 10c) is collected in the chamber (90) and mixed to suppress temperature fluctuations of the air supplied indoors. .

具体的には、図6に示すように、第1〜3の除湿装置(10a,10b,10c)のうち、最初に第1除湿装置(10a)でバッチ動作の切換動作を実行する。このとき、第1除湿装置(10a)からチャンバ(90)内へ供給される空気の温度は、バッチ動作を切り換えた直後が最も高くなる一方、時間の経過に伴って徐々に低い温度になる(図6にT1で示す)。次に、上記第1除湿装置(10a)の切換動作から所定の時間(例えば1分〜4分程度)を置いて第2除湿装置(10b)でバッチ動作の切換動作を実行する。そうすると、第2除湿装置(10b)からチャンバ(90)内へ供給される空気の温度は、バッチ動作を切り換えた直後が最も高くなる一方、時間の経過に伴って徐々に低い温度になる(図6にT2で示す)。そして、上記第2除湿装置(10b)の切換動作から所定の時間(例えば1分〜4分程度)を置いて第3除湿装置(10c)で動作の切換動作を実行する。そうすると、第3除湿装置(10c)からチャンバ(90)内へ供給される空気の温度は、バッチ動作を切り換えた直後が最も高くなる一方、時間の経過に伴って徐々に低い温度になる(図6にT3で示す)。このため、各除湿装置(10a,10b,10c)から同時にチャンバ(90)へ供給される空気は所定の温度差を持つことになる。そして、供給された空気はチャンバ(90)内で混ぜ合わされて、空気の温度が平均化される(図6にTaveで示す)。その後、チャンバ(90)内の空気は室内へ供給される。     Specifically, as shown in FIG. 6, among the first to third dehumidifiers (10a, 10b, 10c), the batch operation switching operation is first executed by the first dehumidifier (10a). At this time, the temperature of the air supplied from the first dehumidifier (10a) into the chamber (90) is highest immediately after switching the batch operation, and gradually becomes lower as time passes ( Indicated by T1 in FIG. 6). Next, after a predetermined time (for example, about 1 to 4 minutes) from the switching operation of the first dehumidifying device (10a), the switching operation of the batch operation is executed by the second dehumidifying device (10b). Then, the temperature of the air supplied from the second dehumidifier (10b) into the chamber (90) is highest immediately after switching the batch operation, and gradually becomes lower as time passes (see FIG. 6 is indicated by T2.) Then, the switching operation of the operation is executed by the third dehumidifying device (10c) after a predetermined time (for example, about 1 to 4 minutes) from the switching operation of the second dehumidifying device (10b). Then, the temperature of the air supplied from the third dehumidifier (10c) into the chamber (90) is highest immediately after switching the batch operation, and gradually becomes lower as time passes (Fig. 6 is indicated by T3). For this reason, the air supplied simultaneously from each dehumidifier (10a, 10b, 10c) to the chamber (90) has a predetermined temperature difference. The supplied air is then mixed in the chamber (90), and the temperature of the air is averaged (shown as Tave in FIG. 6). Thereafter, the air in the chamber (90) is supplied into the room.

−実施形態の効果−
上記本実施形態は、3台の除湿装置(10a,10b,10c)のそれぞれのバッチ動作の切換動作を、3台の除湿装置(10a,10b,10c)が、所定時間(例えば1〜4分)の間隔を置いて順に実行するようにした。このため、各除湿装置(10a,10b,10c)から同時にチャンバ(90)へ供給される空気は所定の温度差を持つことになる。つまり、各除湿装置(10a,10b,10c)からチャンバ(90)へ供給されるそれぞれの空気の温度関係が一定になるため、チャンバ(90)で混ぜ合わされた空気の平均温度も一定になる。これにより、混ぜ合わされて温度が平均化した空気を室内へ供給することができる。この結果、除湿装置(10a,10b,10c)から室内へ供給される空気の温度変動を抑制することができる。
-Effect of the embodiment-
In the present embodiment, the switching operation of each batch operation of the three dehumidifiers (10a, 10b, 10c) is performed by the three dehumidifiers (10a, 10b, 10c) for a predetermined time (for example, 1 to 4 minutes). ) In order with intervals. For this reason, the air supplied simultaneously from each dehumidifier (10a, 10b, 10c) to the chamber (90) has a predetermined temperature difference. That is, since the temperature relationship between the air supplied from the dehumidifiers (10a, 10b, 10c) to the chamber (90) is constant, the average temperature of the air mixed in the chamber (90) is also constant. Thereby, the air which was mixed and the temperature was averaged can be supplied indoors. As a result, temperature fluctuations of the air supplied from the dehumidifiers (10a, 10b, 10c) to the room can be suppressed.
